2 Claims. (Cl. 222-467) (Granted under the act of March 3 amended April so, 192s; 370 0. Q1751) The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates generally to nozzles and more particularly to a nozzle that can be quickly applied to or removed from the filling opening'of a liquid container for the purpose of discharging the contents of the container without loss or waste thereof. Said operation being as successfully performed in the dark as at other times, and its purpose being-especially adapted for the discharge of the contents of gasoline or other liquid or semi-liquids from the standard fivegallon Army container that is-used in the transportation of liquids poured in through its filling opening, into which a captive stopper cap or plug is usually threaded. When the contents of the container are to be discharged, the plug is removed and the improved nozzle is quickly inserted and firmly secured in place and the contents of the container discharged through the nozzle wherever desired and without wasting any of the liquid.

Said removal of the plug from the container, the adjustment of'the nozzle in the opening in the can,-the discharge of the contents of the container, the removal of the nozzle from the container, and replacement of the plug-may all be quickly and successfully accomplished in the dark, as stated above, without any loss of the liquid contents of the container, or by mounting the improved nozzle in the discharge opening of a general supply tank, in which case the container may be refilled during a'total blackout without waste.

The objects of this invention are to attain the above results by a device of simple, durable and inexpensive construction, that maybe quickly attached to the containe permit a free and accurate discharge of the contents of the container and, upon the accomplishment of said function, may be removed from the container and again used repeatedly with practically little or no de- A further object is to provide a structure that consists of parts that are of stock construction, or can be stamped into form for use or such as require a minimum of machine work, and one in which, upon injury, may be promptly repaired and be again returned to functioning conditions.

The above and further objects of this invention will appear in the following description and be finally referred to in the claims.

A preferred embodiment of the invention is shown, but it will be understood that it is for the purpose of illustration and that slight changes in form and minor details of construction may be resorted to without departing from the spirit of the invention or fall beyond the scope. of the claims. I

Similar numerals indicate corresponding Parts in all figures of the drawing in which:

Fig. 1 is a perspective view of a container showing the captive stopper or plug removed from the filling opening in the container and the improved nozzle mounted in said opening in position for the discharge of liquid or semi-liquid contents of the container.

Fig. 2 is an enlarged side elevation of the nozzle within the opening in the container, parts being shown in dotted outline.

Fig. 3 is a similar view taken at right angles to Fig. 2.

Fig. 4 is a vertical section taken on line 4-4 of Fig. 2.

Referring to the drawing by numerals: I indicates a spout or discharge tube that as shown is of a flexible type, but may be of any preferred type or material. The discharge tube is mounted at its inner end in an outer tubular coupling member 2, threaded at 3 into an inner tubular coupling member 4. Said inner coupling member 4 is threaded to receive the outer coupling member, and is provided with an abutment flange 6 and a seat 6 formed on its inner face for the reception of a may be provided by reducing the size of the bore by any preferred means, and is located in such a manner as to receive a ring 8 at the end of the upper portion of the filter and be firmly locked in place by the inner end of the outer coupling member in' such a manner as to prevent leakage and cause the entire discharge of the contents of the container to pass through the filter.

The inner coupling member 4 is provided on its outer face beneath the abutment flange 5 with a cylindrical portion 9 on which is mounted a gasket 10 of compressible material, such as rubber or any other substance, that when compressed in one direction will cause its expansion in another. The gasket is provided with a circumferential extension or fiange ll adapted to rest on the lip I! of the opening of the receptacle when the nozzle is inserted in the opening thereof. Said abutment flange 5 extends to the outer edge of said circumferential extension or flange ll of the gasket and functions to assist in sealing the nozzle in the opening of the receptacle.

Arranged at the inner end of the gasket and filter 1 when used. Said seat 8 adapted to have a snug sliding flt on the inner end of the inner coupling member, is a compression washer i3.

Compression arms "-44 arranged on opposite sides of the tubular members extend through the abutment flange}, the gasket II, and the compression washer I3, and are bent outwardly, or are otherwise provided with means for removably securing the inner ends of the arms ll beneath the washer IS. The arms ll extend beyond the flange 5 and are provided with trunnions IS, on which is mounted a rocker compression lever l6.

Said lever I6 is preferably stamped from a single piece of metal and formed in such a manner as to partly surround the discharge tube as shown at H, to provide a comfortable grip for the operator when detaching the nozzle from the container, and a compact assembly when not in use. The outer end of the lever is deflected at Hi to provide convenient means for obtaining hold on the lever for the purpose of clamping the nozzle into place for use. The lever IE1 is mounted on the ends of the compression arms on trunnion l5 and is formed into eccentrics I! having flanges 20 adapted to present substantial contact wearing surfaces with the flange 5 when the lever is rocked.

As shown, the nozzle is of extreme simplicity, using with few exceptions stock material and is {of such a construction, that by cutting on the heads of the rivets that torm the trunnions IS,

the trunnions may be removed and the entire nozzle disassembled for repair or replacement purposes, and the parts reassembled in the same prompt manner. In disassembling, after removing the trunnions It, the rocker. lever will be released, arms 14 may be slipped from their respective places, thus releasing said arms, the compression washer l3, gasket HI, and by separating the threaded coupling members 2 and 4, the fllter 1 will be released.

In operation, the lever to is adjusted against the discharge tube, in which position the gasket is in its normal condition with its outer sides parallel with the axis of the gasket, or in the form of a cylinder with undistorted sides. In said condition the end of the nozzle is inserted into the opening of the container which requires a reasonably snug, but not necessarily. a tight fit. Too

. tight a fit when adjusting the nozzle in place will cause an unnecessary compression of the gasket and strain on the other parts of the nozzle, with no better results'and with much greater failures of the parts.

By rocking the lever away from the discharge tube, the eccentrics will draw through compression arms, the compression washer toward the abutment flange, thus causing the gasket to bulge outwardly and flrmly fit in the opening of the container and prevent any leakage when discharging the contents of the container. In the axial compression of the gasket, the flange of the gasket that rests on the lip of the opening in the container is clamped between the abutment flange and the lip of the opening in the container, in such amanner as to add materially to the sealing of the joint between said parts.

It may be noted that the opening in the, container may be smooth and the nozzle is intended having a discharge opening, comprising a dis-' charge tube, an outer tubular coupling member on which said tube is mounted, an inner tubular coupling member threaded to said outer member, an outwardly-directed abutment flange on the outer end of the inner coupling member, said flange having a diameter greater than the diameter of the discharge opening of the container so as to overlap the wall immediately surrounding the opening, a compressible gasket mounted on the inner coupling beneath said flange'and adapted to enter the container opening, a flange on the outer end of the gasket,said gasket flange having a diameter substantially corresponding to that of the flange of the inner coupling, a compression washer slidably mounted on the inner coupling member beneath the gasket, compression arms removably connected at their inner'ends to the compression washer and extending through the gasket and abutment. flange, and an eccentrically mounted compression lever pivoted to the outer ends of the compressionarms and adapted to expand the gasket into sealing contact with the wall of the discharge opening and compress the gasket flange into sealing contact with the container wall immediately surrounding the discharge opening. 2. A removable discharge nozzle for containers having a discharge openin comprising a discharge tube, an outer tubular coupling member on which said tube is mounted, an inner tubular coupling member threaded to said'outer member, an outwardly-directed abutment flange on 'the outer end of the inner coupling member, said flange having a diameter greater thanthediameter of the discharge opening of the container so as to overlap the wall immediately surrounding the opening, the inner end of the inner coupling member being necked-in to provide an internal seat, a filter mounted on said seat and clamped between the inner and outer coupling members, a gasket mounted on the inner coupling member beneath the flange thereof and adapted to enter the container opening, a flange on the outer end of the gasket, said gasket flange having a diameter substantially corresponding to that of the flange of the inner coupling member, a compression washer slidably mounted on the necked-in end of the inner coupling member beneath the gasket, compression arms connected at the inner ends to the compression washer and extending through the gasket and abutment flange, and an eccentrically mounted compression lever pivoted to the outer ends of the compression arms and adapted to expand the gasket into sealing contact with the wall of the discharge opening and compress the gasket flange into sealing contact with the container wall immediately surrounding the discharge opening.
